Abstract
THE tenth annual exhibition of electrical, optical, and other physical apparatus, arranged by the Physical Society of London and the Optical Society, was held on January 7 and 8. at the Imperial College of Science, South Kensington. For the first time, we believe, the exhibition, extended over two days. The extent of the exhibits was also greater, two floors of the physics department of the Imperial College being occupied in place of one, as in previous years, the last being 1913. To some extent this expansion was due to a special reason, namely, the inclusion of a supply of German instruments captured during the war, shown by permission of the Admiralty, the Air Ministry, and the War Office. The attendance was very satisfactory. The fact that the annual Conference of Educational Associations was meeting in London during the week allowed many teachers the opportunity to pay a visit, and we believe this was taken full advantage of.
